The coronavirus pandemic has breathed new life into a decades-old technique that can zap viruses and bacteria: ultraviolet light.
Hospitals have been using it for years to cut down on the spread of drug-resistant superbugs and to disinfect surgical suites. But there is now interest in using the technology in spaces like schools, office buildings, and restaurants to help reduce coronavirus transmission once public spaces are open again.
“Germicidal ultraviolet technology has been around for probably 100 years and has had good success,” says Jim Malley, PhD, a professor of civil and environmental engineering at the University of New Hampshire. “Since early March, there’s been just an enormous amount of interest in it, and research funding to institutions around the world.”
The sanitizing effects of UV lights have been seen with other coronaviruses, including the one that causes severe acute respiratory syndrome (SARS). Studies have shown that it can be used against other coronaviruses. One study found at least 15 minutes of UVC exposure inactivated SARS, making it impossible for the virus to replicate. New York’s Metropolitan Transit Authority announced the use of UV light on subway cars, buses, technology centers, and offices. The National Academy of Sciences says although there is no concrete evidence for UV’s effectiveness on the virus that causes COVID-19, it has worked on other similar viruses, so it would likely fight this one too.
Malley’s lab is doing research on how well UVC can sanitize devices and protective gear that first responders use, and have recently been forced to reuse, like N95 masks.
HOLTOP adheres to the “customer-centric” design idea, the disinfection box is light in weight, easy to install, low in energy consumption and effective.
■ Users who have installed the HOLTOP fresh air ventilation system can complete the transformation by installing a disinfection box on the supply air or exhaust side pipeline. The disinfection box can be controlled individually or linked with the fresh air host, which is quick and easy to install.
■ For users of newly installed HOLTOP fresh air ventilation system, they can flexibly arrange and install sterilization and disinfection box on the fresh air side or exhaust side according to the interior decoration situation with the linkage control with the ventilator. Once installed, it will benefit for the whole life.
Besides of the standard disinfection box, Holtop can customized made the sterilization and disinfection products according to the project requirements.
